Trying to Conceive After Miscarriage: How Long to Wait

What does 'waiting three to six months' actually come from?

The traditional advice to wait three to six months before trying again after a miscarriage was largely based on older observational data, practical considerations about accurately dating a subsequent pregnancy, and a general assumption that the uterus needed extended time to recover. More recent research has not supported that longer waiting period for most people.

The American College of Obstetricians and Gynecologists (ACOG) addresses early pregnancy loss in its practice guidance, noting that the uterine lining typically regenerates and that ovulation can return within two to four weeks after an early pregnancy loss 1Ref 1American College of Obstetricians and Gynecologists (2018).ACOG Practice Bulletin No. 200: Early Pregnancy Loss.Evidence-based guidance on early pregnancy loss management, uterine recovery, and timing of subsequent conception attempts. For most miscarriages in the first trimester, there is no structural reason to delay longer than one cycle.

What do current guidelines recommend?

The World Health Organization previously recommended waiting six months after a miscarriage, but that guidance was based primarily on data from low-resource settings and focused on maternal nutrition and spacing. Updated analysis from higher-resource settings has generally found that attempting conception within one to three months of a miscarriage is not associated with worse outcomes — and in some studies is associated with slightly better outcomes than waiting longer.

The American Society for Reproductive Medicine (ASRM) and ACOG both recognize that, for a typical first-trimester loss in an otherwise healthy person, there is no medical indication to impose a mandatory waiting period beyond one full menstrual cycle 1Ref 1American College of Obstetricians and Gynecologists (2018).ACOG Practice Bulletin No. 200: Early Pregnancy Loss.Evidence-based guidance on early pregnancy loss management, uterine recovery, and timing of subsequent conception attempts2Ref 2Practice Committee of the American Society for Reproductive Medicine (2012).Evaluation and treatment of recurrent pregnancy loss: a committee opinion.Definition of recurrent pregnancy loss and criteria for evaluation of recurrent losses. The one-cycle recommendation is largely practical: it helps date a subsequent pregnancy more accurately.

For a second-trimester loss, a surgical procedure (dilation and curettage or evacuation), or complications during a miscarriage, your clinician may recommend a different timeline based on your individual healing.

Does having a miscarriage affect future fertility?

One miscarriage does not increase the risk of another in most cases. Pregnancy loss is more common than many people realize — estimates suggest that roughly 10 to 20 percent of clinically recognized pregnancies end in miscarriage, and the majority of people who experience one go on to have a healthy subsequent pregnancy.

Recurrent pregnancy loss — typically defined as two or more clinical pregnancy losses — is a distinct condition that warrants a thorough medical evaluation to look for treatable causes such as chromosomal factors, uterine structural abnormalities, hormonal issues, or clotting disorders 2Ref 2Practice Committee of the American Society for Reproductive Medicine (2012).Evaluation and treatment of recurrent pregnancy loss: a committee opinion.Definition of recurrent pregnancy loss and criteria for evaluation of recurrent losses. If you have had two or more losses, speaking with a reproductive endocrinologist or maternal-fetal medicine specialist is an important next step.

How do I know when I am emotionally ready?

Physical recovery and emotional recovery do not always run on the same timeline. Grief after a miscarriage is real and valid — even early losses carry significant emotional weight. Rushing into another attempt before you feel ready can increase anxiety and affect your wellbeing during a subsequent pregnancy.

There is no correct answer to when emotionally ready looks like. Some people feel ready to try again quickly; others need more time. If grief is prolonged or significantly impairing your daily life, speaking with a therapist or counselor who has experience with pregnancy loss can be genuinely helpful. Perinatal mental health specialists are one option, and ACOG guidance supports screening and treating mental health conditions in this context 3Ref 3American College of Obstetricians and Gynecologists (2023).Screening and Diagnosis of Mental Health Conditions During Pregnancy and Postpartum: ACOG Clinical Practice Guideline No. 4.ACOG support for mental health screening and treatment in perinatal contexts, including pregnancy loss.

Gale can help you prepare for conversations with your OB-GYN, midwife, or a reproductive specialist about your specific situation.

What should I do before trying again?

Before a subsequent pregnancy attempt, most clinicians recommend:

• Folic acid. Starting or continuing a prenatal vitamin with at least 400 mcg of folic acid supports neural tube development from the earliest weeks of pregnancy.
• A follow-up appointment. Confirm that your hCG levels have returned to zero (for medication or surgical management) or that your clinician is satisfied with your physical recovery.
• Discussing any concerns. If you experienced complications, a recurrence, or have underlying conditions such as a clotting disorder or thyroid disease, these warrant specific discussion before the next attempt.
• Genetic counseling consideration. If a genetic cause was identified or suspected, or if losses have recurred, genetic counseling can help clarify your risk and options.
